It seems like some level is prohibiting the IP addresses of googlebot, as just the user-agent of googlebot does not cause 403. Maybe a piece of software is checking that if user-agent is googlebot then IP must be a google IP, but that software got the IP test backwards.

I had same problem ,if your site is at 40-50% don't worry to much ,try to do again it should let you do again if it doesn't then there is problem with your DNS make sure your google robot txt in your site allows google to follow index
